I face a situation on the jdbc driver and jdk version which are not certified with Oracle and I concern about I can not get any support on it
How about the compatibility between JDK and ojdbc driver version?
Thanks
Yes you can, but not recommended for many reasons.
Check docs recommendation:
...
To use direct-attached storage (DAS) or storage area network (SAN) disks for Oracle ASM, each disk must have a partition table.
Oracle recommends creating exactly one partition for each disk that encompasses the entire disk.
Oracle recommends that you limit the number of partitions you create on a single disk to prevent disk contention. Therefore, you may prefer to use extended partitions rather than primary partitions.
Refer: http://docs.oracle.com/cd/E11882_01/install.112/e48194/storage.htm#CHDDDBDH
Thanks for pointing that out to me.
Now, my intention is to ask our Storage Admin to provide three LUNs as follows:
- OCRVoting Disk: of 3 GB size
- FRA Disk: of 4 GB (we aren't going to enable the DB flashback
- Data disk: depends on the db size.
Is my understanding right?
Thanks in advance.
The FRA is not required. But it is helpful. If you are going to run in archive log mode, then you will want the FRA or some other archive log destination.
I also create a +REDO disk to separate that from the data. Typically, with ASM, I have the following disk groups at a minimum:
+VOTE (also holds OCR)
+REDO
+DATA
and then the optional:
+FRA
